高亮图工具提示在一个页面上覆盖多个图表

我试图使用highcharts将3个图表放到一个页面上 . 每个图表都是具有自己数据的局部视图，并包含带有唯一ID的div .

这一切都很好，期待工具提示 . 在要加载的最后一个图表上定义的工具提示将覆盖其他2个图表上的工具提示 .

任何人都可以解释为什么在这些完全独立的对象之间共享工具提示？

以下是每个部分的highcharts代码：

$('div#' + chartName).each(function (idx, eachChartContainer) {
  if (!$(eachChartContainer).parent().is(':visible')) return;
  $(eachChartContainer).highcharts('StockChart',
  {
      chart: {
          backgroundColor: '#FFFFFF',
          renderTo: chartName[idx],
          isHighcharts: false,
          events: {
              load: function () {
                  var chart = $(eachChartContainer).highcharts();
                  if (chartInterval === '1_day') {
                      chart.series[0].update({
                          tooltip: { xDateFormat: '%a %e %b, %Y %H:%M' }
                      });
                  } else {
                      chart.series[0].update({

容器divs ID在chartName变量中传递

epic变量在div ID中用于标识图表，应该在工具提示中使用（这有点不起作用）
